The director tweeted the photo with the caption "The special Groot version of #GotGVol2 that only Vin Diesel & I have, where every Groot line is printed in English."

As everyone knows, Vin Diesel only has to ever say the lines "I am Groot" in Guardians of the Galaxy (on occasion he'll say "we") but each time he says the line it's delivered differently, the meaning changing every time.

While it's part of the fun and charm of the character that we can impress our own ideas of what Groot means onto the goofy tree man, part of us really wants to know what Groot says in English.

Like, really really wants to know.

We do know something about what Groot will be like in the upcoming film thanks to executive producer Jonathan Schwartz, who said "he doesn't have the wisdom and experience" he did in the first Guardians.

"He's a younger Groot and a more rambunctious Groot.

"The question is, is he the same Groot, just smaller? Or is he a different Groot that's sprung up from the seed of the first Groot?"
